Abstract: A semiconductor integrated circuit device includes a semiconductor integrated circuit chip, a IC package enclosing the semiconductor integrated circuit chip, lead terminals, and dummy terminals. The lead terminals are partly embedded in the IC package side by side along its opposed sides, and the dummy terminals are partly embedded in the IC package at both ends of a line of the lead terminals. These terminals are electrically connected with the circuit formed in the chip. One end of each terminal protrudes from either of the opposed sides of the IC package and has a connection to be connected with terminal electrodes of a packaging substrate. The dummy terminals are made wider and/or longer than the lead terminals so as to make their connections larger than those of the lead terminals, thereby enhancing their reliability in point of machine-resistance and heat-resistance.

Abstract: An IC card comprises a module with an electric circuit and two panels adhered to each other to cover the module between them. The two panels are adhered with an adhesive with a sufficient adhesion strength and seals the module with no path of air to the outside of the IC card. Airtight sealing of the IC card in realized in various ways. For example, a groove having a varying width is provided in one of the panels for applying an adhesive, while a groove engaging to the groove is provided in the other of the panels. When the two panels are adhered to each other, gas channels may be formed in the groove at portions with narrower widths, while an adhesive in the groove at portions with wider widths fills the gas channels due to viscosity. In another way, a protrusion provided in one of the panels has an edge opposite to a groove provided in the other of the panels. Thus, the groove is kept air-tight. In a different way, an adhesive having a high viscosity at curing temperature is used.

Abstract: An IC card including an electric circuit board and have face and back metallic panels that include a housing and are attached to a resin frame. The IC card has a discharge pattern formed on the electric circuit board for discharging static electricity applied to the metallic panels, a conductor elastically disposed between one of the metallic panels and the discharge pattern for electrically coupling one of the metallic panels with the discharge pattern, and a ground pattern formed on the electric circuit board with the ground pattern separated by a given distance A from the discharge pattern for routing the static electricity to a card connector. The given distance A is a distance necessary for the static electricity to start discharging at a given voltage. A given distance needed for discharge can be maintained precisely through a simple manufacturing process. A fluctuation in discharge start voltage can therefore be minimized. This results in a highly reliable product.

Abstract: In an IC card and a manufacturing method therefor, an adhesive is applied between core layers in the vicinity of an opening in which an IC module is placed. The core sheet layers held between adhesive layers can easily be deformed when heat and pressure are applied. Therefore, a gap formed between the card substrate and the IC module is filled. Furthermore, the gap from the IC module is narrower at the corners of the IC module than conventionally shaped openings. As a result, gaps at the corners of the IC module after integral molding are prevented. Therefore, the gap between the IC module and the card substrate can be reliably filled during molding.
